MECHANICAL MOVEMENT.

SPECIFICATION forming part of Letters Patent No. 414,641, dated November 5, 1889. Application file August 12, 1889. Serial No. 320,500. (No model.)

To a-ZZ whom it may concern:

Be it known that we, RICHARD LONGD'EN HATTERSLEY and JAMES HILL, subjects of the Queen of Great Britain,residing at Keighle'y, in the county of York, England, have invented an Improvement in Mechanical Movements, of which the following description, in connection with the accompanying drawings, is a specification.

This invention has for its object the construction and arrangement of a system of gearing consisting of upper and lower partlytoothed cylinders, into connection with one or the other of which at predetermined times may be made to gear any one or more or the whole of a series of intermediate gear-wheels, which operate, in connection with a corresponding series of toothed crank-wheels, for the purpose of moving, when put into oper ation, one or more or all of a series of levers, this arrangement operating to lock or rigidly hold the levers at each extremity of their respective movements in such a manner that any force acting upon the said toothed crankwheels through or by the levers they operate, as by said levers having to'overcome some weight or power before they are and when being and after. they have been moved, is withstood by a stationary shaft upon which the said wheels are mounted, while at the same time the movements of their series of K intermediate gear-wheels are freely permitted for the purpose of allowing thesame to be placed into or out of gear with one or the other of the partly toothed cylinders, which, when rotated, operate the toothed crankwheels by means of their intermediate wheels, and so effect such interchange in the positions of the levers as may be predetermined by the arrangement of the pins or pegs in peg-lag or pattern surfaces, which are our ployed for raising or allowing to fall the intermediate wheels, as above described, into gear with the upper or lower partly-toothed cylinder.

The object of this invention further extends to the construction and arrangement of the series of toothed crank-wheels, their respective intermediate wheels,lever-arms, and connecting-rods in such a manner that while the same are in their respective operating positions no one part thereof can become detached from another; yet by releasing one binding-plate any single part may be detached or the whole may be taken away together. lVe attain this object by the mechanism illustrated in the accompanying drawings, in which'- Figure 1 is a part-sectional side elevationof the parts forming our improved mechanical movement Fig. 2 is a top view of the parts shown by a section of Fig. 1 on line a: y, together with certain of the parts that are not shown in Fig. 1, on account of the said Fig. 1, being in section. Fig. 3 is a sectional detail showing the construction and arrangement of the jointings of the connect ing-rods' to their respective levers. Fig. 4 is a sectional detail showing the gear for imparting motion to the partly-toothed cylinders.

Similar letters referto similar parts throughout the several views,

The parts marked A form, the frame-work for the bearance of the motor parts.

Upon the driving-shaft a, which may be rotated by any common and well-known mo tor, is mounted the gear I), which imparts mo tion through the gear 0 to the partly-toothed cylinder d, and this in the direction indicated by the arrow 6. From the cylinder d motion is imparted by means of the gears f f to the other partly-toothed cylinder g, and this in the direction indicated by the arrow 6'.

Mounted loosely, so as to revolve upon the stationary or fixed shaft 72, which is carried by the frame-work A, is theseries of toothedcrankwheels 7c, and also loosely mounted upon this shaft h is the series of levers attached to or formed on each of which, in a suitable position,'is a pin or stud, (shown in broken lines, Fig. 1,) upon which is loosely mounted an intermediate wheel m, arranged to'be (when in operating condition) continuously in gear with its corresponding wheel in the series of wheels 7:. The outer ends of the levers Z are made to extend, as shown, and are respectively coupled to the levers n by their respective rods 0. The levers n are operated or raised by the pegs or pins 19, (which form the pattern-surface on the peg-lags 13, and the positions of which maybe altered, as is usual,

the same being common and well-known.) Consequently so also are the levers Z and theirrespective wheels m while the reverse movement of these parts is effected by gravity. Thus when a pin 19 is brought in a common and well-known manner by its cylinder 19 so as to raise one or other of the levers n, one or other of the wheels m will be lifted; into gear with the toothed cylinder d, and when the said pin 19 is moved from this position then the Wheel m, that it had raised, will descend and fall into gear with the toothed cylinder g. This cylinder d has (as also has the cylinder g) a sufficient number of teeth to impart a semi-rotation toall-or any of the wheels in the series m, and, the pitch of the teeth in each of the wheels in the series m agreeing or corresponding with that of the wheels in the series 70, when one or the other of the wheels m is placed in gear, as above described, with the cylinder (Z, and thus rotated, its corresponding wheel 70 will be semi-rorated-say from the position shown in Fig. .1.by which means the crank-pin s will be brought into a posit-ion diametricallyopposed to its former position, while when the said wheel m, which was placed into gear with the cylinder d to eifect the interchange of position, is placed into gear with the cylinder g, and is thereby operated, the crankpin sis caused to assume its former position. Now, as both the positions assumed by the pin 8 are so arranged relatively to the positions of the outer ends of the lovers tthat any force exerted through that lever in this said series t, to which it is coupled by one or the other of the connecting-rods Q), will act in a straight line through the center of the wheel 76, said force will be withstood by the shaft. h. The lever 1, hinged at 2 and moved in one direction through the medium of the rod 4: by a cam mounted upon or attached to rotate with the toothed cylinder g and in the other direction by the spring 3, is employed for rigidly holding the levers Z in their raised or lowered position by means of its broad outer end 5 being brought between the ends of levers Z, so that the series of wheels m are firmly held while being rotated, as above described.

By arranging the series of wheels is upon the stationary shaft h as above described we are enabled to utilize each of the wheels is to keep its adjoining connecting-rods o in position relatively to the other of said Wheels k, with the exception of the one on the outside, and this is kept in position by the plate 10, Fig. 2, which is rigidly mounted upon the same shaft h. In a similar manner, also, are the wheels m and rods 0 kept in contactwith their respective levers Z. However, in this case an ordinary button-head is employed, the same being formed on the pins, as at Z Z, on the outermost lever Z for keeping the outermost wheel and rod in position. As will be seen, it is only necessary to release the outer plate 10, and then the whole of the other parts are free to be detached, so far as connection with shaft h is concerned; Again, the jointings of the rods 21 to their respective levers t are so formed, as shown by Fig. 3, that by moving the said rods 1* from their operating position, which is somewhat horizontal and at right angles relatively to the levers t, tothe some:

What perpendicular position shown by Fig. 3, or about into a straight line with the'said levers t, the said rods 1; are freed from connection with the pins 15', and so may be detached for repairing or other purposes.

We claim In a mechanical movement, the combination of the partly-toothed cylinders d and g, means for imparting motion to these cylinders d and g, the toothed gearing-wheels m, mounted as described, the levers Z, pattern devices forops crating these levers Z, the crank-wheels is, mounted to rotate upon a stationary shaft h, the shaft 72-, the rods v, having theirjointings in connection with the pins 25, formed as shown, the levers t, and the plate 10, all these.

said parts being constructed and arranged to operate substantially as specified.
